BAL NORCO 21700292 MOTOR REPLACEMENT KIT R25078 R25079 21900004 21900005

Restore reliable operation to your BAL/Norco slide-out system with the BAL/Norco G5.5 Motor Replacement Kit (Part #21700292). This complete service kit includes everything needed to replace both left and right motors with the updated extended-shaft design and matching bushings — a comprehensive retrofit upgrade rather than a single-component swap.

Complete Extended Shaft & Bushing Retrofit

This isn't just a motor swap — it's an upgrade kit. The redesigned extended shaft motors and matching bushings address the wear points of the original design, giving you a more durable, longer-lasting slide-out drive than a simple like-for-like replacement. Both motors in this kit are equipped with 10-tooth sprockets.

Wide Replacement Compatibility

The 21700292 kit replaces the following BAL/Norco part numbers:

• R25078 — Right Hand Top Mount or Left Hand Bottom Mount Motor with 10 or 12-tooth sprocket
• R25079 — Left Hand Top Mount or Right Hand Bottom Mount Motor with 10 or 12-tooth sprocket
• 21900004 — Right Hand Top Mount Motor with 10-tooth sprocket
• 21900005 — Left Hand Top Mount Motor with 10-tooth sprocket

If Your Slide Is Acting Up

If you're trying to confirm whether the motors are actually the cause of your slide-out issues before ordering this kit, our guide to diagnosing an RV slide-out that moves slowly or gets stuck can help you narrow down the problem first.

Installation Made Easier

The kit includes left and right drill templates for accurate hole placement, plus a tension gauge for proper system setup after installation — both of which take a lot of the guesswork out of the retrofit. BAL also provides a step-by-step installation video to walk you through the process: Watch the BAL Motor Replacement Kit installation video here.
